22aO-Spirostanols

Fig. 7.13 Steroickil sapogenins of the 22aO-spirostanol type occurring in the genera Solanum and/or Cestrum, respectively (for examples of species see Table 7.1). Compounds with names highlighted in bold were discovered in certain solanaceous species if not, they had been discovered already before in other plant families. Compounds in parentheses do not represent the genuine aglycone but a returanged stable derivative of an nnstable genuine one (for details see text). For references see Table 7.1...

Fig. 7.14 Steroidal sapogenins of the 22P0-spiiostanol type occurring in Solanwn hispidum euid S. torvum, respectively (for details and references see Table 7.1). Neosolaspigenin was erroneously characterized as 22aO-spirostanol type in the original report for solaspigenin see Fig. 7.13...
